I personally don't think the .45WinMag is a good idea even in a large frame Ruger. The accepted safe maximum for large frame Ruger .45's is 32,000CUP and the .45WinMag has a maximum operating pressure of 40,000CUP. Equal to the .44Mag. It would make no sense anyway as you can get better performance out of the .45Colt at less pressure, due to its greater powder capacity. It would be a novelty at best with no practical advantage over more practical cartridges.

Definitely not a good idea for an N-frame.
